EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail based on drawing.

<Embodiment 1>

First, the electronic balance 1 used in Embodiment 1 of the present invention will be described. 1 to 3 are views showing an example of the electronic scale 1. 1 and 2, the electronic scale 1 includes a scale main body 2 and a lid 3 capable of closing the top surface of the scale main body 2.

The circumferential surface of the scale main body 2 is covered with a relatively flat resin case 4, and on the upper surface of the case 4, as shown in Fig. 3, a weighing dish on which the object to be measured A is placed ( 5) and various operation buttons such as a display portion 6 for displaying the weight of the object to be measured A, an ON / OFF switch 7, a reset button 9, and the like.

Inside the case 4, although not shown, a weight detection device for measuring the weight of the weighed object A placed on the weighing dish 5, a control board having a calculation section or a storage section, a power supply, and the like are incorporated. Preferably, on the side of the case 4, a connector 11 for detachably connecting a storage medium B such as a USB memory is formed (Figs. 1 and 2).

The lid 3 is attached to one end of the scale body 2 so as to be freely undulated, and is click-stopped in a standing state up to a predetermined angle. In addition, a camera 12 such as a CCD camera and a lighting device 10 such as an LED are provided on the surface of the lid 3 facing the scale main body 2. When the lid 3 stands up to a predetermined angle and stops clicking, the camera 12 is capable of imaging the top surface of the scale main body 2 including the weighing pan 5 and the display 6, and Installed at an angle.

The lighting device 10 automatically emits light when the object to be weighed A is placed on the weighing dish 5, or emits light by operating an operation button, and includes the weighing dish 5 and the display section 6 Light is irradiated toward the upper surface of the scale body 2 to be said. Further, the angles of the camera 12 and the lighting device 10 may be adjusted.

After the lid 3 is raised to a predetermined angle to expose the surface of the scale main body 2, the ON / OFF switch 7 is operated to be in a driving state, and then the weighed object 5 is weighed ( When A) is mounted, the weight detection device measures the weight of the object to be weighed (A), and the weight is displayed as a number on the display portion (6).

Subsequently, the camera 12 photographs the upper surface of the scale main body 2 including the weighing plate 5 and the display portion 6, and the image data captured by the camera 12 is stored in the storage portion of the control board. . At this time, the camera 12 is preferably photographed so that the weight of the object A placed on the weighing plate 5 and the object A displayed on the display portion 6 are simultaneously put in one image. Do. The imaging by the camera 12 may be performed automatically after the weight is displayed on the display unit 6 or may be performed by operating an operation button. Further, after imaging by the camera 12, trapezoidal correction processing may be performed as necessary. For example, as shown in Fig. 9, in order to facilitate trapezoidal correction processing, a marker having a predetermined color or shape at two or more points (for example, four corners) of the upper surface of the balance body 2 (61) may be formed. In this case, by performing trapezoidal correction using the marker 61 as a starting point, accurate and reliable processing can be performed.

In addition, if the storage medium B is connected to the connector 11 of the scale body 2, the image data captured by the camera 12 can be stored in the storage medium B. In addition, the electronic balance 1 measures the weight of the object to be measured (A) and the image data captured by the camera 12, such as Bluetooth (registered trademark), wireless communication standards such as WiFi, or other wired or wireless communication. The means may be used to send electronic devices (not shown) outside the electronic scale 1.

4 is a diagram showing another example of the electronic balance 1. In this example, the camera 12 and the lighting device 10 are provided on the upper surface of the scale body 2. In addition, the lid body 3 is a scale body portion including a weighing plate 5 and a display portion 6 when the lid body 3 stands up to a predetermined angle on a surface facing the scale body portion 2 It has a reflecting means (13) for reflecting the image of the upper surface of (2) toward the camera (12). As the reflecting means 13, for example, there is a mirror or a metal evaporation layer having a high reflectance.

Accordingly, when the lid 3 is raised at a predetermined angle to operate the ON / OFF switch 7 and the object A is placed on the weighing dish 5, the weight of the object A is displayed on the display unit 6 ), And since the reflecting means 13 reflects the image of the upper surface of the scale main body 2 toward the camera 12, the camera 12 and the object to be weighed A on the weighing plate 5 , The display portion 6 whose weight is displayed is imaged together. Other configurations and methods of use are the same as those in the embodiments shown in Figs. 1 to 3, so that the same reference numerals are given to the same parts, and detailed description is omitted.

Next, the weighing system 1000 of the processed material including the electronic balance 1 is demonstrated. 5 is a block diagram showing an example of a functional configuration of the metering system 1000. The weighing system 1000 includes a management device 100, an input means 200, and an electronic balance 1.

The management device 100 has an input means interface 110, an electronic balance interface 120, a processing part correction unit 130, a storage unit 140, and an output unit 150, and the management device 100 is central Each processing unit is logically realized by having a processing unit (CPU) and a storage unit, and the CPU executing a program stored in the storage unit. The management device 100 may be a single device, or a computer system realized by a plurality of devices performing parallel or distributed processing. The management device 100 is typically disposed in the same network as the input means 200 or the electronic scale 1 or is directly connected, but the input means 200 or the electronic scale 1 is provided through a wide area network such as the Internet. The family may be placed remotely. For example, the management device 100 may be a smart phone, a tablet terminal, a personal computer, or the like, or may be mounted as a so-called cloud service.

The input means interface 110 is connected to the input means 200 through wired or wireless communication. The input means interface 110 acquires information and the like for identifying a processed product through the input means 200. The input means 200 may be, for example, a barcode scanner, a keyboard, an image recognition unit capable of image recognition, an IC tag reader, and the like, but is not limited thereto. The input means 200, for example, reads a barcode or the like written in the instruction sent from the dental clinic, and acquires identification information (hereinafter, simply referred to as identification information) that can uniquely identify the order, It outputs to the input means interface 110.

Moreover, the input means interface 110 may acquire information regarding processing which the user inputs using the input means 200. The processing information may include, for example, materials used for processing, information identifying a processing base, information identifying a processing operator, information identifying an orderer, information identifying a processing process, and the like. In the processing step, for example, in the case of the manufacturing work of dental pores, processes such as the receipt of materials, the delivery (removal) of materials, the pressing, the polishing, the polishing, and the recovery of surplus materials are included. Whenever at least one of these processes is performed by the user, the metering system 1000 can be used to meter and record the material.

In addition, in general, identification information is stored in connection with information regarding ordering in a management system (not shown). The ordering information may include, for example, information on the type of processed product (such as a tooth portion), the material to be used, and the size of the processed product.

The electronic scale interface 120 is connected to the electronic scale 1 to enable wired or wireless communication. The electronic balance 1 outputs at least a measurement of the weight of the processed product to the electronic balance interface 120.

Preferably, the electronic balance 1 includes the image data captured by the camera 12, that is, the object A placed on the measuring plate 5 and the object A displayed on the display unit 6 It is also possible to output image data in which the weight of the product is simultaneously put in relation to the weight of the processed product. The electronic balance interface 120 outputs the weight of the processed product to the processed powder correction unit 130. Alternatively, when the process for correcting the processed powder is unnecessary, the electronic balance interface 120 outputs the weight of the processed product to the storage unit 140 or the output unit 150.

The processing component correcting unit 130 acquires a measurement value of the weight of the processed product output by the electronic scale interface 120 in order to add the weight of the processed product to the weight of the processed product, and the measured value The process of correcting the processed powder multiplied by a constant coefficient greater than 1 (about 1.05 to 1.15) is performed. For example, the processed powder correction unit 130 holds a correction table as shown in Fig. 6 in a storage area not shown. The correction table in FIG. 6 is a table in which the finished weight and the coefficient of the processed product correspond. In this case, the processed powder correcting unit 130 refers to the correction table, and acquires a coefficient corresponding to the weight of the processed product acquired by the electronic balance interface 120. Then, the weight of the processed product is multiplied by a coefficient to obtain the weight after correcting the processed powder.

In addition, the format of the correction table is not limited to this, and may be configured such that coefficients can be specified, for example, depending on the type of the processed product (such as a tooth portion), material, size, or a combination thereof. In this case, the processed powder correcting unit 130 uses the identification information of the above-mentioned instruction, to obtain information such as the type of the processed product (such as a tooth portion), material, size, etc. from the management system of the instruction not shown. Can be acquired. Alternatively, the processed powder correction unit 130 may directly acquire these information input by the user through the above-described input means 200 or the like.

In addition, instead of the correction table, the processed powder correction unit 130 may have a conversion formula, a statistical model, a machine-trained model, etc. that output the counted or corrected weight by inputting the weight of the processed product.

The processed powder correction unit 130 outputs the weight after the processed powder correction is performed to the storage unit 140 or the output unit 150. Preferably, the identification information acquired by the input means interface 110 and the image data acquired by the electronic scale interface 120 are output in association with the weight after correction of the processed powder.

The storage unit 140 acquires and stores the weight after the processing powder correction from the processing powder correction unit 130. Alternatively, the weight of the processed product is obtained and stored from the electronic balance interface 120. Preferably, the weight is stored in association with identification information or image data.

The output unit 150 obtains the weight after correcting the processed powder from the processed powder correcting unit 130 and outputs it to the outside. Alternatively, the weight of the processed product is obtained from the electronic balance interface 120 and output to the outside.

Preferably, the weight is output in association with identification information or image data.

The information stored by the storage unit 140 and the information output by the output unit 150 are, for example, written on a delivery note, written on a bill, registered on an order management system, and processed material in a manufacturer's establishment. It can be used for inventory management.

Conventionally, in dental laboratories, the amount of purchase or the amount of export is managed by manually inputting the amount of purchase into the management system when the material is purchased, or by manually inputting the amount of discharge into the management system when the processing person takes out the material. However, it has been difficult to manage the amount of material used. This is because the amount of the material used for machining was unknown because it was not possible to measure the amount of the material that was lost during the machining process such as cutting and polishing. According to this point and the present embodiment, it is possible to automatically calculate and record the amount of the used processing material or the amount of the processing material lost in the processing process in the element elements of the processing process. Thereby, inventory management of the processed material can be performed with reference to the recorded data. That is, it is possible to specify the amount of used material and the amount of inventory of the processed material at any point in time so far. In addition, past performance values can be used to estimate the amount of used and inventory of processed materials at any point in the future. In addition, for each processing base or processing worker, the amount of processing material used and the weight of the processing product can be specified to calculate the loss rate of the processing material. Such information is useful, for example, when instructing a machining worker. In addition to this, the weight data (a measured value of the weight of the workpiece A or a numerical value indicating the weight after the correction is performed on the measured value) is placed on the image data photographed by the camera 12, that is, the weighing plate 5 A proof that the weight data is definitely of the object to be measured (A) by storing or outputting the weight of the object to be weighed (A) and the weight of the object (A) displayed on the display section (6) in association with the image data. Can leave

In addition, since the calculation of the amount of used processing material has been performed based on experience in the past, the calculation standards are varied by processing personnel and dental laboratories, and it has been a factor that causes the client to have an opaque feeling. However, according to the present invention, it is possible to calibrate the processed powder on a consistent basis. For this reason, the processing cost details are not false and fair to the orderer.

In addition, some dentists purchase materials themselves, and deposit the processed materials in dental laboratories for processing. In such a case, the output unit 150 may calculate the inventory of the processed material based on, for example, the purchase performance of the processed material and the use performance (or the predicted value), and present it to a dentist or the like. Do. Furthermore, the output unit 150 may, for example, issue an alert urging the purchase when a predetermined inventory amount falls below a threshold value, or may automatically execute an order processing.

In addition, even in a dental laboratory, it is a merit that the machining component correction is performed on the same standard for all processing personnel. For example, the output unit 150 can also determine whether or not there is a gap or irregularity in processing technology depending on whether there is a difference between the amount of material processed and the amount of processed material corrected.

<Embodiment 2>

7 shows the configuration of the weighing system 2000 according to the second embodiment. The weighing system 2000 includes an electronic balance 1, a management device 100, and a terminal device 300.

The electronic scale 1 in Embodiment 2 has a scale main body 2. The structure of the scale body 2 is the same as in the first embodiment. That is, the scale main body 2 has a case 4, and on the upper surface of the case 4, a weighing plate 5 on which the object A is weighed, and a display unit for displaying the weight of the object A (6), ON / OFF switch (7), reset button (9), and the like are formed. Inside the case 4, a weight detection device for measuring the weight of the object A placed on the weighing dish 5, a control board having a calculation section or a storage section, a power supply, and the like are built in.

The terminal device 300 has a data logger unit 310 and an information input unit 320. The terminal device 300 is preferably a portable information processing terminal, and is typically a smart device such as a smartphone or tablet terminal. The terminal device 300 has hardware such as a CPU, a memory, an input / output device (including an output device such as a wired or wireless communication device, a display device, an input device such as a touch panel), and a camera, and the CPU executes a program By doing so, the functions of the data logger 310 and the information input unit 320 are logically realized.

The data logger unit 310 acquires an image of the display unit 6 of the electronic balance 1 on which the weight of the object A is displayed, using the camera of the terminal device 300. When photographing, the data logger 310 may display a target, a frame, or the like for aligning the position of the display 6 on the screen of the terminal device 300. The user shoots the image of the display unit 6 so as to match the position to this target or frame. Then, the data logger 310 performs character recognition processing within the region indicated by the target or frame in the character recognition processing described later. Thereby, the target area of the processing for recognizing the characters in the image can be limited, so that the time for the character recognition processing can be shortened and the recognition accuracy can be improved.

Or, as shown in Fig. 10, on the electronic scale 1, a marker 62 (target or frame, etc.) capable of recognizing the data logger 310 is drawn at a predetermined position near the display unit 6; You may have. The marker 62 is, for example, a target representing a disadvantage (typically a corner portion) of an arbitrary region (typically a rectangular region) surrounding the display portion 6, and a line segment representing a part of the region Or a figure or a frame showing the shape of the area. As the marker 62, a target or a frame is typically formed on the electronic balance 1 by printing on the upper surface of the scale body 2 or attaching a predetermined seal or the like that can be attached to the electronic scale. In the character recognition processing described later, the data logger 310 first recognizes this target or frame from among the images, and then performs character recognition processing within the region indicated by the target or frame. As a result, the target area of the processing for extracting characters from the image can be limited, so that the time for character recognition processing can be shortened and the recognition accuracy can be improved.

In addition, after imaging the data logger unit 310, a trapezoidal correction process may be performed as necessary. In order to facilitate the trapezoidal correction process, a marker 61 having a predetermined color or shape may be formed on, for example, four corners on the upper surface of the scale main body 2. In this case, by performing trapezoidal correction using the marker 61 as a starting point, accurate and reliable processing can be performed. In addition, the target or frame as a marker 62 defining an area including a display portion drawn on the upper surface of the scale body portion 2 described above is useful as a marker 61 for trapezoidal correction of an area including the display portion ( You may use it.

When the image including the display unit 6 is acquired, the data logger 310 recognizes the characters in the image, and outputs the recognition result as numerical data indicating the weight of the object A to be weighed. Since character recognition processing from an image, that is, OCR (Optical Character Recognition) can be realized by a known technique, a detailed description is omitted here. In addition, as described above, in the present embodiment, the data logger 310 displays a target, a frame, or the like for aligning the position of the display unit 6 at the time of shooting on the screen of the terminal device 300 or the display unit By forming a target or a frame or the like capable of recognizing the data logger 310 at a predetermined position near (6), it is possible to improve the time and precision of the character recognition processing.

In addition, the data logger 310 may perform character recognition processing in order each time an image is captured, or may perform a character recognition processing in a combination after multiple images are captured. In addition, the data logger 310 may have a user interface for confirming whether or not the character recognition result is correct to the user, and modifying the character recognition result to the user as necessary. For example, a screen may display a photographed image, a text recognition result based on the image, a button for accepting the text recognition result, a keypad for editing the text recognition result, and the like.

Here, when the data logger 310 photographs the display portion 6 of the electronic scale 1, it is preferable to simultaneously put the weighed object A placed on the weighing plate 5 into the image. It is possible to leave a proof suggesting that the numerical data output by the data logger 310 is clearly indicating the weight of the object to be measured A.

The data logger 310 transmits numerical data indicating the weight of the object A to the management device 100 using a wired or wireless communication device of the terminal device 300. The communication device can transmit data using, for example, a wireless communication standard such as Bluetooth (registered trademark) or WiFi. Moreover, the data logger 310 may transmit the photographed image to the management apparatus 100 in association with the weight of the object to be measured A. Thereby, the information which proves the measurement result can be reliably left.

More preferably, the data logger unit 310 performs the process for correcting the processed powder with respect to the numerical data indicating the weight of the object to be measured A, and then the weight data after the corrected processed powder is processed with respect to the management device 100. Send. The content of the processing powder correction processing is the same as the processing of the processing component correction unit 130 described above. That is, the data logger 310 calculates the weight data after the correction of the processed powder by multiplying the numerical data representing the weight of the object to be measured A by a constant coefficient greater than 1 (about 1.05 to 1.15). The coefficients may be given by an arbitrary conversion formula, a statistical model, a machine-trained model, or the like other than the correction table as shown in FIG. 6. Further, the coefficient may be varied depending on the type of the processed product (such as a tooth portion), material, size, or the like. In this case, information such as the type of the processed product (such as a portion of the tooth), material, and size may be directly input through the input device of the terminal device 300 or may be provided through the information input part 320 described later.

The information input unit 320 uses the camera or input device of the terminal device 300 to acquire information, etc. for identifying the processed product. For example, the camera of the terminal device 300 reads the barcode or the like described in the instruction sheet, and acquires identification information that can uniquely identify the order. The information input unit 320 transmits the acquired identification information to the management device 100. Further, the information input unit 320 may transmit an image including a barcode or the like to the management device 100 together. Preferably, the identification information acquired by the information input unit 320 and the weight data acquired or generated by the data logger 310 are both output to the management device 100. In other words, identification information and weight data are associated and output to the management device 100.

In addition, the data logger unit 310 and the information input unit 320 may be mounted as a unit. For example, the display unit 6 of the electronic balance 1 in which the camera of the terminal device 300 displays the weighed object A placed on the weighing dish 5 and the weight of the weighed object A. ) And the barcode or the like described in the instruction sheet are simultaneously photographed. The data logger 310 and the information input unit 320 each process the weight data (numeric data representing the weight of the object A or the weight of the object A) from this one image. Numerical data after implementation) and identification information may be acquired. Thereby, the user can more easily record the weighing result.

The management device 100 has an input unit 160, a storage unit 140, and an output unit 150. The management device 100 may be an information processing device, preferably a personal computer, or a server computer mounted as a so-called cloud service. The management device 100 has hardware such as a CPU, a memory, an input / output device (including an output device such as a wired or wireless communication device, a display device, and an input device such as a keyboard), and the CPU inputs a unit by executing a program ( 160), the functions of the storage unit 140 and the output unit 150 are logically realized.

The input unit 160 receives identification information acquired by the information input unit 320 and weight data and image data acquired or generated by the data logger unit 310 from the terminal device 300 through a wired or wireless communication device. do.

The storage unit 140 stores the weight data after correction of the processed powder in association with identification information and image data. The output unit 150 outputs the weight after the correction of the processed powder to the outside. Preferably, the weight after correction of the processed powder can be output together with identification information and image data. The information stored by the storage unit 140 and the information output by the output unit 150 are, for example, written on a delivery note, written on a bill, registered on an order management system, and processed material in a manufacturer's establishment. It can be used for inventory management.

In addition, when the data logger unit 310 of the terminal device 300 does not perform the processing powder correction processing, the management device 100 may have the processing powder correction unit 130 as in the first embodiment. In this case, the processed powder correcting unit 130 performs the processed powder correcting process based on numerical data indicating the weight of the object A to be measured obtained by the data logger 310.

<Embodiment 3>

In the third embodiment, instead of the terminal device 300 recognizing the characters displayed on the display portion 6 of the electronic scale 1, the electronic scale 1 transmits the weight data, which is the measurement result, to the terminal device 300 do. Thereby, the character recognition process in the terminal device 300 can be omitted.

8 shows the configuration of the metering system 3000 according to the third embodiment. The weighing system 3000 includes an electronic balance 1, a management device 100, and a terminal device 300. Compared to the second embodiment, the electronic balance 1 and the terminal device 300 differ in some configurations, but other configurations are the same. Here, the differences from the second embodiment are mainly described, and the descriptions of the points that match are omitted.
